Bad 02 Sensor?
2016 C7 LT1
Code P015BO2 sensor delayed response - lean to rich (bank 1 sensor 1).
At 46k miles this went off with my check engine light and it was only on for 4 days then turned off. Now at 51k miles its on again. I do drive my car a **** ton and do not beat on it.
Does anyone believe this to be a faulty signal?
Is it a serious problem?
Is there a recall (I know there was some sort of faulty capless gas signal recall we had in the past)?
Can someone point me to the location of this O2 sensor?
I cant find one on the internet so far. Should I change the O2 sensor or is there another fix?
I cant get to changing it till the weekend, if it has to be changed. Thank you!

If the CEL comes on and then clears (and since you have a scanner apparently), check the history. That the light went back off means the condition was clear for x number of engine start/stop cycles. But as it threw the same code a few K miles later, I would at least check the sensor (and/or connection to it)

I would like to check it. But I do not know where it is located. I know in general where the sensors are located but I do not know which one bank 1 sensor 1 is.
Also I bought a fuel injection cleaner (techron) - waiting for the tank to go near empty. I haven't put any additives in the engine ever.

That code you gave (P015BO2) doesn’t sound right. You sure you typed it in correctly?
